Opening a gnome terminal can take 5-10 seconds on a system that's been running for a while (and with another gnome terminal already open).
Solution
Checking /etc/hosts, you can see something like this:
127.0.0.1 localhost
127.0.1.1 inspiron
... add your hostname to the first line, like this:
127.0.0.1 localhost inspiron
127.0.1.1 inspiron
(Replace "inspiron" with your hostname of course)
You should notice a crazy performance boost.
mike@mike-desktop2 ~ $ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 michi-power4
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
$ sudo nano /etc/hosts
$ cat /etc/hosts
127.0.0.1 localhost michi-power4
127.0.1.1 michi-power4
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
Reasons
This is a fix for the new system that was started back in edgy where the hostname was split off to 127.0.1.1, the problem is that some applications still look for the host name @ 127.0.0.1, so to keep those applications happy and running smoothly you simply need to add the host name where those applications expect it to be.
